The system supports vertical navigation for all lateral leg types except for CA, CI, FA, FM, HA, HM, PI, 

VA, VD, VI, VR, and VM.  Vertical constraints are not retained in stored flight plans.

The Vertical Navigation (VNV) feature provides vertical profile guidance during the enroute and teminal phases 

of flight.  Guidance based on specified altitudes at waypoints in the active flight plan or to a direct-to waypoint is 
provided.  It includes vertical path guidance to a descending path, which is provided as a linear deviation from the 
desired path.  The desired path is defined by a line joining two waypoints with specified altitudes or as a vertical 
angle from a specified waypoint/altitude.  The vertical waypoints are integrated into the active flight plan.  Both 
manual and autopilot-coupled guidance are supported with a Garmin autopilot.
